Most intelligent persons in the world (10 people with highest IQ) 2023
Discover the world's smartest minds, from Ainan Cawley's record-breaking IQ to the extraordinary journeys of intellectual luminaries.
In every era, individuals of exceptional intelligence are born, and while some of them achieve widespread recognition, others lead more private lives. Many of these geniuses make profound contributions that have a lasting impact on the world. The measurement of intelligence, particularly in the context of the smartest individuals globally, is commonly accomplished through the utilisation of IQ (Intelligence Quotient) tests.
The concept of IQ was first introduced by the German psychologist William Stern in 1912. It serves as a quantifiable metric for assessing an individual's intellectual capacity, determined through specialised psychological assessments.
It's important to note that the quantification of intelligence is not static; it evolves over time and can be influenced by an individual's circumstances and condition.
In the Western world, several well-known IQ tests are employed to gauge intelligence. These include the Hans Eysenck questionnaire, the Stanford-Binet test, the Wechsler test, Raven's Progressive Matrices, and various others.
Today, we evaluate the intelligence of contemporary geniuses using numerical IQ scores. Here is a list of the top 10 living individuals with the highest IQ in the world in 2023:

What is IQ: How tests are conducted and what their results mean
The concept of IQ is a measure of intellectual aptitude, with the average IQ score typically falling within the range of 90 to 110 points among most individuals.
It is generally believed that only around 1% of the global population boasts an IQ score exceeding 140 points, a category often referred to as "geniuses."
The exceptionally rare group of individuals with an IQ surpassing 190 points is estimated to consist of only one person per billion.
It is important to note that IQ cannot be precisely calculated for historical figures who lived before the advent of standardised IQ tests.
However, some experts attribute high levels of intelligence to renowned historical figures such as Leonardo da Vinci, scientist Mikhail Lomonosov, inventor Nikola Tesla, chemist Dmitri Mendeleev, physicist Isaac Newton, and philosopher René Descartes. Albert Einstein's IQ is estimated to be around 190 points.
The intelligence of these historical luminaries is primarily gauged through their remarkable contributions and groundbreaking works that have left an indelible mark on human knowledge and progress.
